Ingredients
- 4 St Pierre Brioche Burger Buns
- 20 oz good quality beef mince
- Pinch sea salt and black pepper
- Several sprigs fresh thyme, leaves only
- 3 tbsp light mayonnaise
- 1 clove garlic, crushed
- Drizzle truffle oil
- 1 small onion, peeled and sliced thinly
- 2 tsp olive oil
- 1 tbsp butter
- 3.5 oz chestnut mushrooms, sliced
- 5 oz swiss cheese such as Emmental or Gruyere, grated
- 2 oz (approx. two large handfuls) baby spinach leaves
- Gem or romaine lettuce leaves, washed
- 2 vine tomatoes, thinly sliced
Method
- Make the burgers – put the minced beef into a bowl and season well salt and pepper then add some of the thyme leaves. Using clean hands, mix everything together then divide the mix into 4
- Shape into patties, each slightly wider than the buns (as the burgers will shrink slightly when they cook) and place on a large plate. Cover and put into the fridge while you prepare everything else
- Mix the mayonnaise, a pinch of black pepper and half of the crushed garlic (keep the rest to one side) together in a small bowl then drizzle in a little truffle oil to taste – you’ll only need a small amount
- Heat the oil in a frying pan and gently fry the onions with a pinch of salt for 20 minutes
- Meanwhile, in a separate pan, fry the mushrooms in the butter for about 5 minutes then stir in the rest of the thyme leaves. Lift out and keep warm
- Add the burgers to the pan that the mushrooms were in and cook for about 5 minutes on each side, pressing them down slightly as they cook to keep their shape
- Check they’re cooked all the way through then sprinkle over a little of the cheese. Lift out onto a plate
- Add the spinach to the pan and allow to wilt for a minute with the heat on minimum (or even turned off)
- Lightly toast the burger buns if you like then spread a little truffle mayo over each of the bases
- Add some lettuce and tomato then the burgers with melting cheese
- Divide the mushrooms and onions between the burgers then sprinkle over the rest of the cheese
- Finally add some wilted spinach and pop on the lids
Enjoy those Mushroom Swiss Cheese Burgers. Bon appétit!
